JSX not recognized in vscode

[egovelox]

I cannot get correct JSX in vscode (despite using the deno extension)

I followed the readme, getting started deno install // but here I added --no-check because it was not ok dext create myproject and inside pages/index.ts vscode displays the following error on the first jsx <> : Cannot find name 'React'.deno-ts(2304)

I really have no clue how to fix this ! Thanks !
